Abstract: An artificial-satellite antenna mounted in an artificial-satellite including a satellite body, the artificial-satellite antenna includes solar cell panels, radiators, and conductors that are mechanically and electrically connected to the solar cell panels, in which the solar cell panels and conductors are used as reflectors.

Abstract: A computer produces predictions throughout a raster field in response to point data, by obtaining a partially empty matrix of point data, filling a matrix of extrapolated raster data by dilating the point data in a first convolutional neural network, and generating a matrix of aggregate raster data by combining the extrapolated raster data with organic raster data in a second convolutional neural network.

Abstract: A method of generating an aggregate forecast includes obtaining historical forecasts for a number of time steps and at least one location, obtaining historical conditions for the time steps and the at least one location, training a machine learning algorithm to produce an aggregate historical forecast in response to the historical conditions and the historical forecasts, and producing an aggregate current forecast by running the trained machine learning algorithm on current forecasts. The historical forecasts and the current forecasts vary in at least one of spatial resolution or temporal resolution, and include a first forecast that is valid for a first time step and a second forecast that is valid for a second time step.

Abstract: A method for estimating a right-under point position of an on-orbit object includes an imaging step of capturing an observation image of an on-orbit object, together with a known object of which an orbit is known, a first right-under point position calculation step of calculating a right-under point position with respect to a center point of the observation image, and a second right-under point position calculation step of calculating a right-under point position of the on-orbit object based on the right-under point position with respect to the center point of the observation image.

Abstract: A debris removal device includes: an end mass adapted to approach debris to be removed; a debris capture device separably-mounted on the end mass; and a tether connecting the debris capture device and the end mass to each other. The debris capture device includes a harpoon adapted to penetrate into the debris, a shooting device adapted to shoot the harpoon, a guide member positioned to come into contact with the surface of the debris to adjust the shooting angle of the harpoon with respect to the surface of the debris, and a switch that sends the shooting signal to the shooting device. When the harpoon is penetrated into the debris, the end mass is separated from the debris capture device, and the tether is released into outer space.

Abstract: Provided is a vapor jetting device including: a box-shaped casing; a propellant holding unit that is placed in the casing and forms a space for holding a propellant; a gas storing unit that is placed in the casing, forms a space that is divided from the propellant holding unit by a partition wall including a communication hole, and stores gas; a machine housing unit that is placed in the casing, forms a space that is divided from the propellant holding unit and the gas storing unit by partition walls, and houses machines; a nozzle that is connected to the casing and ejects the gas to an outside; a gas flow path that is formed in the casing and supplies the gas stored in the gas storing unit to the nozzle; and a heater that is placed in the casing and heats at least the gas storing unit.
